"Well... After careful study yesterday, I found that this incense is indeed special. The materials used in it are far more than I imagined, and it seems to contain some mineral powder. As for what exactly it is, I can't figure it out for the time being," Wu Sang sighed.

Upon hearing this, Yuan Ming, although he had anticipated it, still slightly furrowed his brows.

"Hehe, don't worry, my friend. My family has been making incense for generations. With my thirty years of experience, I will eventually figure out its formula as long as I put in some effort. Today, I will teach you the basic process of making incense. This will also cost you," Wu Sang said, rubbing his hands together. He had noticed Yuan Ming's change in expression and gave an awkward smile.

"Of course, the family's unique skills are also an intangible wealth. How much silver should I pay?" Yuan Ming nodded.
